What it is
Most sentences in a legal text describe, permit or oblige. A performative formula does something else: it performs the act it names, so the wording is not a report of a declaration or an enactment but the declaring and enacting itself. Trosborg, working in Austin's speech act framework, gives the purest form of the declaration as "I/we (hereby) declare" followed by a proposition, and draws the consequence that sets this unit apart: a will written in the wrong formula is not a will at all.
The enacting formula is the case with the widest reach, an explicit performative that establishes the illocutionary force of an entire text; it stands where preamble turns into law. The Westminster formula, Be it enacted by the King's most Excellent Majesty, by and with the advice and consent of the Lords Spiritual and Temporal, and Commons, carries the binomial advice and consent inside the performative, a pair of the kind binomials-and-doublets describes.
Routine formulae next door are also selected rather than composed, but usage warrants them and their force is social; here the warrant is an instrument, the force legal. Whether a text type admits an equivalent at all is terminology's ground; this record keeps the formula by which the genre constitutes itself.
Where the fixity comes from
The warrant is doubled, doctrine and instrument. The doctrine is constitutive: where the formula is the act, an amended formula is a different act or none. The instrument side splits between placement and wording. Guideline 7 of the Joint Practical Guide fixes the placement, the standard sequence of title, preamble, enacting terms and annexes where necessary; Guideline 7.3 sets the enacting terms apart as the legislative part. The wording is fixed one level deeper, in the model each legal order keeps for its own acts: every language version of an EU regulation prints its own version of the same adoption and closing formulas. For the wording to change, the order's way of enacting would have to change; no editor holds that pen.
Consequences for translation
These formulas are met in two situations that must not blur: making a language version of an instrument, and translating an instrument into a language that is not one of its versions.
- In a language version the formula is found, not made. The Dutch text of a regulation opens the enacting terms with the formula every Dutch version prints; producing it is placement of a fixed form, not translation of the English.
- The empty approximation tier is this record's claim, not an oversight. In an instrument there is nothing to approximate: the target legal order supplies its own formula, or the text is not that instrument. An informative translation of a foreign statute does not enact; the formula there is reported speech, and the unit is no longer at work.
- The modal surface belongs to the version, not to the translator. The English closing formula of a regulation carries shall; the Dutch version prints present indicatives. A reviser who restores the modal is composing, and the force was never in the modal.
- The formula marks where the preamble ends and the enacting terms begin, and cross-references hang on that boundary. In revision these lines are checked against the order's model text, not against the source, and a deviation is a finding.

- Target: HEEFT DE VOLGENDE VERORDENING VASTGESTELD:
- Comment: Commission Implementing Regulation (EU) 2026/124 of 14 January 2026, the line between preamble and Article 1 in the English and Dutch versions. Dutch inverts to verb-final and replaces this with a cataphoric de volgende. A translator composing from the English would write HEEFT DEZE VERORDENING VASTGESTELD, a wording no Dutch version prints; the formula is found in the version, not derived from the source.

- Comment: The Swiss Data Protection Act of 25 September 2020, enacting preamble, German and French versions, both authentic. The performative verbs are not translations of each other: beschliesst resolves, arrête decrees. German separates legal basis from consultation, gestützt auf against nach Einsicht in; French opens both with vu. A translator composing from the German would write décide; the version prints arrête.
